I would do a proactive fluid/filter change in a couple months just to be sure.

But yeah, limp mode is super rough on a 722.6, and I could see how you shed some material off the clutches during those events.

They use the computer to soften up the shifts by modulating the hydraulic pressure. When you are in limp mode it is just the valve body operating in emergency mode without any computer assistance and you are just getting dumped into second gear.
